Effects Of Context And Word Class On Lexical Retrieval In Chinese Speakers With Anomic Aphasia

Keywords

Chinese; connected speech; picture naming; word class dissociation

Abstract

Background: Differences in processing nouns and verbs have been investigated intensely in psycholinguistics and neuropsychology in past decades. However, the majority of studies examining retrieval of these word classes have involved tasks of single-word stimuli or responses. Although the results have provided rich information for addressing issues about grammatical class distinctions, it is unclear whether they have adequate ecological validity for understanding lexical retrieval in connected speech that characterises daily verbal communication. Previous investigations comparing retrieval of nouns and verbs in single-word production and connected speech have reported either discrepant performance between the two contexts with presence of word class dissociation in picture naming but absence in connected speech, or null effects of word class. In addition, word finding difficulties have been found to be less severe in connected speech than picture naming. However, these studies have failed to match target stimuli of the two word classes and between tasks on psycholinguistic variables known to affect performance in response latency and/or accuracy.
